She's been missing for over a month, despite a $150,000 reward for information regarding her disappearance, but the parents of Metallica fan and 20-year-old Virginia Tech student Morgan Harrington are not giving up. They won't stop searching until Morgan is found, and according to Metallica bassist Robert Trujillo, the band is praying for her safe return.

"I was crushed," Trujillo says in a recent interview, about learning of Harrington's disappearance; he added that the case has been ever-present on the band members' minds. "Stuff like this just really, really bums me out, especially when you are a parent and you have children. I mean, it's the worst thing that you could ever imagine. And of course, you know, we're all hoping for the best and just praying that she's alive. It really hit a sour chord with us and bummed us out."

Harrington hasn't been seen since Metallica's Oct. 17 concert, which she attended with friends. She became separated from the group, and ended up outside the venue, where there is a no re-entry policy. Police have very few leads, but say Morgan was last seen hitching for a ride on a nearby bridge. Investigators also believe she may have tried to use another concert-goer's phone to make a call.

The National Center for Missing and Exploited Children has gotten involved with the case, fielding calls and taking any information about Harrington's case.

Trujillo is the second member of the band to comment on the case. Last month, guitarist Kirk Hammett told reporters that the band was "staying positive that she will be found soon," and added that "we are all hoping for the best and praying for her and her family. We all have children and as parents ourselves, it's our worst nightmare for a child to go out and not come back home. We empathize with that greatly, so we are doing what we can to help find her. We are staying positive."
